The washer, or if grcutvlseparation is (insired than twang,- more or them, are used for without increasing the total diameter of the bearing and also permitting the same angle of the member 5, to wit, degrees, or thereabout, to be retained, and also the same distance between the centers-of the balls. Ob viously the washers may vary in thickness as the size of the balls varies.

It may sometimes happen that a bearing is to be equipped with balls of such size or the diameter of the hearing may be such that there will be no necessity for any washer at all, inwhich event the angle rings composing the cup will be brought close to gether, so that they aibut against each other, as shown in Fig. 6. Also since these bearings are made in many sizes and for many different uses, some of them requiring unusual strength, I sometimes reinforce the angle member 5 of the cup rings by so proportioning the jacket that its turned in edges shall, during the crimping operation, be brought in contact with the outer surfaces of the members 5 as shown at 9 in Fig. 7, thus acting; as braces for them.

Those who are familiar with such matters will at once understand that many departures may be madefrom the details of con struction described and illustrated by me and still the essentials of the invention be retained. For instance, the cup rings or sections may be turned up from solid bar metal, also the jacket in some cases need not be made to entirely lap around the edges of the cup sections, but simply to lap on to them sufficiently to prevent their separation. I prefer the construction shown, however. Although the forming dies will in many cases make the bearings so accurately that no additional machine work will be necessary, still for special uses some slight and relatively inexpensive machine work may be desirable, especially if the bearings are standardized and must be interchangeably used.

Although I have illustrated my invention as applied to an outer bearing having an inward presentation, clearly the reverse form will be produced by a mere reversal of the parts, so that they shall have an outward presentation. In short, although I shall herein claim certain of the details of construction described and illustrated above,

because they are, as I believe, new and I know them to be useful yet I believe my invention to be broader than such details and I shall therefore also claim-it thus broadly.

I claim:

1. As anew article of manufacture, acomplete, self-contained and self-supporting ball bearing unit having two cup rings made of sheet metal, each having a member parallel with the axis of the bearings andanother sheet metal jacket which embraces and confines the cup rings, the edges of said jacket being crimped about the edges of the parallel members of the rings and extended to and adapted to brace the angular members of said rings, an interior hearing or cone and balls between the cup rings and the cone. i

3. As a new article'of manufacture, a bearing having two cup rings made of sheet metal, each having a member parallel with the axis of the bearing and another member at an angle thereto arranged side by side, a parallel sided washer between the meeting edges of said rings, a sheet metal jacket which surrounds said rings, the edges of which jacket are crimped about the outer edges of the parallel members and extend to and are adapted to brace the angular meinbers of the rings, an interior bearing or cone,

and balls between the cup rings and the cone.

In testimony whereof I have si ned in name to this specification in the presence of two subscribing witnesses.
